Specification of Letters Patent.

Patented Apr. 16, 1918.

Application filed October 27, 1916. Serial No. 128,123.

To all whom it may concern:

Be it known that I, CLYDE T. DEAN, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Ink-Saving Attachments for Embossing-Presses, of which the following is a specification.

My invention relates to improvements in ink saving attachments for embossingpresses, the present application being an improvement on the construction forming the subject matter of my Patent No. 1,198,198, granted September 12th, 1916, for ink-saving attachments for embossing presses.

It has been found that the solvent-applying mechanism disclosed in my above referred to patent is of such arrangement and construction that the supply of the solvent exhausts too rapidly and that, with the construction shown in said patent, it is impos 'sible to completely drain the solvent receptacle, it being necessary to keep said receptacle well filled in order to obtain proper results.

It is the object of this invention, therefore, to provide a construction in which the objections above mentioned with regard to the solvent-applying mechanism are avoided, and wherein an exceedingly eflective solventapplying device is produced and which, at the same time, is of durable and economical construction.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed. I

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is a partially sectional front elevation of an ink-saving attachment embodying the invention, showing the same mounted between the side plates of an embossingpress,

Fig. 2, is a section taken on line mw of Fig. 1,

Fig. 3 is a detail perspective view of one end of the solvent-receiving trough or receptacle, showing the manner of support of the supporting bar therein, and

Fig. 4 is an enlarged detail section taken on line Y-Y of Fig. 2.

The preferred form of construction as illustrated in the drawings is shown as mounted upon an embossing-press of which fragmentary portions are disclosed, the side plates of the supporting frame of the embossing-press being indicated at 1. The wiping web 2 is mounted to be moved through the embossingpress in the usual manner, being unwound from a suitable feed roll and finally wound upon a suitable waste roll 3. The wiping strip, as described in my before mentioned patent, is employed for removing surplus ink from the face of the die or printing surface, and is moved through the machine with an intermittent movement so that fresh portions of the wiping strip are brought successively into engagement with the die or printing surface. The function of the attachment forming the subject matter of this application is toremove from said wiping strip the ink thus collected thereby and to retain and save {his ink which heretofore has been a total oss. 1

As described in my said patent, the wiping strip after leaving the embossing-press, passes over a solvent-applying device where the ink covered surface of the wiping strip is moistened by a solvent, said strip thereafter passing over a cotiperating plate 1 where the ink which has been loosened by the solvent, is scraped from the strip. Said plate 4 is suitably supported in a frame 5 which, in turn, is supported at its ends in the frame members 1. With the scraping platel cooperates a backing roller 6 which serves to hold the wiping strip in engagement with the upper edge of said plate 4. Said wiping strip thereafter passes under a guide roller 7 whence the same passes upwardly to the receiving roller 3. Below scraping plate 4 is arranged a trough 8 into which the ink removed by said scraping plate is deposited and collected, the lower end of said trough being adapted to deposit the ink into any suitable receptacleprovided for the purpose. The improvement forming the subject matter of the present application is the solvent-applying mechanism above referred to, this mechanism comprising an elongated receptacle or trough 9 which is supported at its ends by arms 10, said arms 10 having upwardly opening slots 11 which are engaged by lugs 12 projecting from the ends of said receptacle. Arranged at the upper side of said receptacle is a longitudinally extending bar 13 having extensions Li atits ends which loosely engage. in upwardly opening slots 15 provided in the ends of said receptacle. Arranged upon and embracing the central portion of bar 13 is a solvent-applying member 16 in the form of a substantially rectangular sheet of absorbent material, such as felt, which-is bent upon itself to embrace said bar, the depending registering ends of said strip being secured together asby stitchingand the same depending into the receptacle to the bottom thereof as seen'in the several views. The arrangement is such'that the wiping strip 2 will contact with the upperbight portion of said member lfi and thus be coated with the liquid absorbent which is provided in the receptacle 9 and which is automatically drawn-upwardly in said member 16 through capillary attraction or in precisely the same manner as the conventional lampwick. IViththis arrangementdt will be seen that a device is provided which occupies a very limited amount of space, as distinguished from the roller employed for this purpose in my before mentioned patent, the trough being thus adapted to carry a greater quantity of solvent, as will be readily understood. Also withthis arrangement the solvent-applying device will be operative until the supply of solvent is completely exhausted from the receptacle or trough 9, which is not the case where a roller is empl0yed,-un less;the roller is of'su'ch large diameter as to project downwardly to the very bottom of the trough. The bar 18 is held against rotation through the snug engagement of the ends thereof with the slots1'5, and the member 16 is correspondingly held against rotary movementthrough secure engagement of the same with said bar, the latter being flattened or ofelongated rectangular form in cross section, as seen in Fig. 2. Helical springsl? are preferably employed engaging under the ends 14 of the bar 13 for pressing the solvent-applying member into contact with the wiping strip, as will be readily understood.

While I have illustrated and described the preferred form ofconstruction'for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of eonstructionset forth, but

flames e2 iilhllfl amine may rte obtained m desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

I. In an ink-saving attachment for embossing-presses and the like, the combina tion with a movable ink wiping strip, of means for applying a solvent to said strip comprising a receptacle for solvent open at its upper side, and having angular recesses at its ends, a bar provided at the upper side of said receptacle having angular endsengaging in said recesses whereby said bar is held against rotation but is readily removable, and a solvent-applying member of flexible absorbent material folded over and supported by said bar for contact of its fold with said strip, the parts of said member at opposite sides of its foldv depending from said bar into said receptacle and being stitched together under said bar, whereby said member is held on said bar but is left uncompressed for free capillary action.

2. In an ink-saving attachment for embossing-presses and the like, the combination with a movable ink wiping strip, of means for applying a solvent to said stripeompris ing a receptacle for solvent open at its upper side, and having angular recesses at its ends, a bar provided at the upper side of said receptacle having angular ends engaging in said recesses whereby said bar is held against rotation but is readily removable, a solvent-applying member of flexible absorbent material folded over and supported by said bar for contact of its fold with said strip, the parts of said member at opposite CLYDE T.
